Compute market snapshot — observed spot prices: cheapest rentable ask per GPU class in USD/hour. $0.25 per query via x402 USDC on Base, Arbitrum One, or Algorand. Asks are ephemeral — re-observe before any decision. Paid output (shape only, no values): {market, generated_at, classes: [{gpu_class, cheapest_rentable, median_price_per_gpu_hour_usd}], caveats}. One payment buys one fresh observation; values are yours only after the payment settles.

[SIGNAL+PROOF] One official signal record for any signal_id and entity: current reading against the OFFICIAL threshold ladder (band, distance-to-action) plus a 5-year same-season percentile so you can tell routine from unusual. 180+ signals across macro, weather, hazard, shipping, filings, crypto and lifecycle lines. Free coverage check first at /gauge/coverage. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

Counts describe directory coverage, including testnets. Each resource groups the same URL, HTTP method or MCP tool across sources. A catalog sighting records published terms. A live 402 records the endpoint’s reply to an unpaid request.
